Very simple to use...simple to install...great value. No sense to filter water through an RO unit and not know if the RO unit is making a positive impact to water quality. This unit make that analysis very simple

Super EZ to install. I have it after the RO then at final output as suggested. Works like a charm. I had purchased a used RO/DI unit and this meter takes all the guess work out changing filters.

Works great easy to set up comes with velcro to mount it on your ro/di system or somewhere else. Only con is it feels cheap it would be nice if it was made out of a metal box or harder plastic pushing the on button makes the whole front panel bend in. So it feels like im going to break it lol other than that works great.

It was easy for my wife and I to get this piece mounted on the wall and quick to start. It read very well the first time as it updated our input and output very fast. I would recommend this product to all, including beginners.

I've had one of these little guys for about 4 years now. It was worked flawlessly and I've never replaced the battery. I love not having to guess when it's time to replace my filters.

Great little toolBy Jimon 7/20/2010

This piece of equipment will take the headache out of knowing when to change filters. I used to record how much water went thru my RO unit by reading the water meter coming into the house. Not any more. Just a simple switch ON and then the slide switch for input water and output water and I know instantly if I need to change filters or not. It has saved me replacing my filters too early or waiting until the dreaded algea takes over my tank.

This tool is one of the most useful pieces of equipment to have, and has paid for itself many times over. It has saved me from installing filters before they expire or from perofrming expensive water changes to clear algea outbreaks if the filters were way past thier useful life.. A SUPER tool.

Never guess again trying to determine if your RO and DI innerds need changed! I purchased 2 of these Dual TDS Monitors. I know how efficiently everything is working. A perfect system...can't ask for more! Great price, too!!

We have this TDS meter on a RO/DI unit at work, and it still working flawlessly after years of use. I recently picked up the same meter for my own personal system. Great Price, Easy Install, and Great Functionality.

Set one probe between membrane and DI and one after the DI. This was I will be able to tell when it's time to switch the filters. Great product I just wish the cables were slightly longer.

If you have a RO/DI system this product is a must. It is a quick reference to determine how your RO/DI system is performing. The dual channel data is very helpful.
